Question 1

What does it mean to have an oversized bearing?

Accepted Answer

When an engine block is machined, the bearing bores can become slightly larger. An oversized bearing has a slightly thicker outside diameter to compensate for this, ensuring a proper fit and oil clearance. Always measure your clearances to confirm fitment.

Question 2

What other parts should I replace when replacing my main bearings?

Accepted Answer

When replacing your main bearings, it's best practice to also replace your rod bearings at the same time. You should also inspect the crankshaft for wear and have it machined if necessary. Always use new bolts and proper torque when reassembling your engine.

Question 3

How do I know if I need an oversized bearing?

Accepted Answer

You'll need to measure the main bearing bore in your engine block after it has been machined. If the bore is larger than the standard size, you'll need an oversized bearing to maintain the correct oil clearance. Consult your engine builder for the correct size.
